Retro Fit Round Cable Gland

amazing solution, works as advertised and so easy to install. Amazon engineering

Nice product! Worked better than others I've tried using. Replaced another brand product that simply broke do to weak chrome plastic. This thing is sturdy but takes patience to install. It's great you can add it after the wires are already pulled through hull. Seals out water. Comes with rubber holes drills at a few standard sizes. May need tweaking.

Exactly at I needed!

I like it kinda hard to put back together after you take apart but guess it better for water intrusion .

Works well as described

Works great

It would work great if the parts had a chance to fit together, but the design folks must have skipped engineering school the day that manufacturing tolerances were taught. To get the inner rings to mate, I needed to use silicon oil (silicon, as not to hurt the plastic) - and still needed a hammer to get them to mate - never to come apart again (as was the design intent). Then, for further frustration, the outer ring needed a clamp to get the pieces to mate together. They eventually can be made to work, but you may need some anger management counseling afterwards.

It provides a tight secure fit, I used it for a uv-c light power cord that goes through the air handler cabinet, so needed something that one kept cord in place, since it connect to a 4 pin and could unplug itself if slack, and also need air tight for Iaq purposes. it's very snug and not going anywhere, drilling the rubber thing to right size is not easy, but doesn't have to be perfect either, as clam will tighten around it.
